speciflcation of Letters Patent.

Application filed September 11, 1913. *Serial No. 789388.

To all 'whom tt may concem i Be it known that I, PAUL W. LAMSON, a citizen of the United States, residing at Cleveland, in the County of Cuyahoga and State of Ohio, have invented a new and useful Improvement in Steam-Pipe Insulation and supports, of which the following is a -full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification, in which- Figure 1" is a side elevation partially in section of a conduit containfig a steam or other pipe supported therein., Fig. 2 is a vertical transverse section on the line II II of Fig. 1. Fig. 3 is an 1%nd view pf the steam p'pe support; and ig. 4 is a side elevation thereof.

This invention relates to an improvement in insulated pipe supports which are incased in terra cotta pipes and are also incased in insulating material. v

The invention is more particularly directed to the support for the pipe and is arranged to normally maintain 'the pipe in a central position' within the terra cotta pipes, and at the same time ermit the conveyer pipe to expand and contract.

A further object of, my invention isto provide a support in which. the conveyer'` pipe will be supported at suitable intervals on pedestals through the medium of the terra cotta pipes. v V

The precise nature of my invention will be best understood by reference to the accompanying drawi'ngs, which will now be described, it being premised, however, that changes may be made in the details of construction and the general arrangement of the parts, without departing. from the spirit' and scope of my invention, as defined in the appended claims.

In the drawings the numeral 2 designates the supporting pedestals which are spaced at proper intervals within the trench in which the conduit is placed. After the pedestals have been formed the lower half of the terra cotta casings 3 is placed in position in the usual manner. After these sections of the casing have been properly placed, the conveyer pipe 4 is placed in position; and connected to the conveyer pipe about' centrally above each of the pedestals 2 'is a supporting bracket 5. I bracket comprises ai body portion and down- This supporting tion of the pipe support, and a clamp ng wardly extending lugs"6 at each end thereof. These lugs are forked, and rotatably mounted on pins Tare rollers 8 which are seated within the forks. The upper face of the body portion of each of these supports is provided with a plurality of lugs 9 which Patenteu nec. 22, 1 914. I

are concaved to fit the pipe 4. 'Connected to the bottom of' the body portion is a metal band or 'strap 10, which 'is passed around V the top of the pipe, and the ends 'are connected to each other by means of a bolt 11 to clam the supports in position on the pipe. fter these supports are secured to the pipe at the proper points, the pipe will be supported directly from the terra cotta casing 3, which is inturn supported on the pedestals 2. After the pipe has been placed in position it is covered between the supports with a heat-insulating lagging of any well knowntype, while the supports are covered with 'a composition from which the lagging is made, so that the entire length of the pipe is insulated. After the insu'lating material has been'placed in position'the up-' per sections of the terra cotta casing are placed in position and the trench is filled.

By the use of a support such as I have shown and described, I am able to support the conveyer pipe directly upon the terra cotta casing which is in turn supported on the pedestals.

The advantages of my invention result from the provision of a support for incased ppes or conduits in which the supports and the pipe are entirely surrounded by the terra cotta shell, which will prevent moisture from entering the sealed Conduit. Further from the provision of a support which is connected directly to the conveyer ?pipe in such a manner that the' pipe is allowed to tact with the stationary surface, thereby. avoiding all danger of chafing the insulating material surrounding the pipe. Further from the provision of means for supporting the pipe directly on the terra cotta shell so that the conveyer 'pipe will always assume its proper position when placed in the casing. r

I claim: V.

1. A pipe support having a c'oncaved seating surface for the pipe, a plurality of rollers connected to said support, a flexible' clamping strap surrounding the body porscrew connected to the' ends of the strap';

V there being a space between the heat-insulatsaid supports extendin through the heatinsulating material, an supporting rollers connected to said projections engaling the inner wall of the casing; substanta y as de- -scribed.

In' testimonj whereof,-I have hereunto set my hand. v
